Typical maximum excitation voltage is around 15 volts. Wiring. Rice Lake 6-Wire Standard Load Cell Cable6-wire cable is most commonly used in commercial applications where multiple load cells are employed. For the best experience on our site, be sure to turn on Javascript in your browser. The extra sense pair are used for sensing excitation supply to load cell. Written by Indrek Luuk. Also from most specifications the Red wire is the "output". Red Electric Cable. In any event, the cable should be well shielded and have sufficient cross section (at least 0.2 mm2) to limit the voltage drop along its length. To create a full bridge you want to connect at least two of these load cell parts to form a 4-wire connection: simulate this circuit. Depending on the model, the load cells may have a cable with 4 or 6 wires plus the screen. This will compensate for any voltage drops over the length of cable between them. Connecting positive and negative voltage to the black and white wires (either way) will result in the red wire being, ideally, exactly half the voltage. VKK1-4 /VKK1R-4 Junction box. The sense wires of the 6 wire load cell can be connected to the sense terminals of the weight indicator to measure and adjust the amplifier on the actual voltage of the load cells. Table of content: Video Tutorial. The full-bridge cells come typically in four-wire configuration. We recommend that you do not shorten the cable of a 4 wire load cell if it is too long; it is better to coil up the cable. The Sense (reference) wires are connected to the sense terminals of the weight indicator, so that this can measure and adjust the amplifier on the actual voltage that arrives to the load cells. usually incorporates either three, four, five or six vibrating wire strain gauges mounted parallel to the cells axis of symmetry and equally spaced. If an installation engineer wants to shorten the cables, they can do so without compromising the load cell performance. I dont know if there is a connection problem or something else, i have even tried to do it through example VIs but it does not work either.

(As above use an ohm meter to verify the wire connections of your parts.) When connecting 4 wire load cells together into a junction box before the weight indicator/transmitter, we recommend using a dedicated 6 wire load cell cable (for example the Thames Side polyurethane cable CA-PU-5.7MM-6C) to connect the junction box to the indicator/transmitter. The 6-wire cable is best suited for longer runs where remote sense lines can be used With 4-wire load connection, the transmitter operates in a ratiometric mode to eliminate errors due to power supply variations. The main difference in function of these 2 types is that load cells with a 6 wire cable can compensate for variations in the actual excitation voltage they receive from the amplifier/indicator. With long cables, there will be a drop in voltage from the original value supplied by the amplifier/indicator and the advantage of a 6 wire load cell is that this drop in voltage can be quickly and effectively compensated without it affecting the weight measurement. The output between them should be equal or to a value specified in the datasheet. To keep your login experience secure, we request you to verify your identity. The 6-wire load cells are therefore preferred over those with 4 wires, also on these load cells there are no limitations in the event the installer wants to shorten the cables. Please confirm your Mobile Number to receive the. The 6-wire models, in addition to having the terminals of power supply + and power supply – and signal + and signal -, have 2 additional wires called Sense + and Sense – which may also be denominated reference. The resistance of an electrical cable varies depending on temperature and length, given that we can say that as the temperature and the distance changes there is a voltage drop that the 6-wire system allows to be compensated without affecting the measurement. This is the test for load cell output resistance. Livraison rapide Produits de qualité à petits prix Aliexpress : Achetez malin, vivez mieux These are sometimes called +Reference (or +Ref) and -Reference (or -Ref). Think of these 3 wire load cells as potentiometers; the red wire is the wiper. A hopper or tank system may use four load cells with one under each foot to measure weight. Active 6 years, 2 months ago. www.groupfourtransducers.com. Hi, I am trying to acquire data from a 3133_0 - Micro Load Cell (0-5kg) - CZL635 . The two sense wires are capable of measuring the actual excitation voltage seen at the Wheatstone bridge inside the load cell, therefore the mV signal from the load cell can be adjusted according to the actual excitation it experiences. What advantages do the 6-wire load cells have with reference to the compensation of the voltage drop on the cables? When connecting a 6 wire load to a 4 wire system, the sense wires should be connected to the same place as the input wires. : 1-VKD2R-8. In any event, the cable should be well shielded … Rice Lake EL147 Standard Load Cell Cable, 6 Wire, 100 ft.
